Meanwhile the other cylinder is extended in readiness for the next pack to be transferred.
Abstract: A cigarette packing machine with a plurality of passageways leading from a hopper, includes an ends testing device (16, 16a) for individual cigarettes, so that faulty cigarettes can be rejected from the hopper before the cigarettes are ejected in groups at the bottom of the passageways (2).Leading from the hopper are two channels (6, 8) feeding each of the passageways. In one embodiment of the invention cigarettes are held up for ends testing in alternate channels by suction ports (14) formed in inclined surfaces leading to each passageway. In a second embodiment a set of horizontal reciprocating wires (30, 32) acts as an escapement mechanism.
Abstract: A measuring apparatus for the quantitative evalution of peripheral venous drainage disorders and arterial blood flow disorder in man. In clinical practice, this invention makes it possible on the one hand to objectively detect the changes in cutaneous circulation under physical strain, while it can also be employed, on the other hand, to detect obstacles to venous flow in the extremities. The measuring apparatus detects peripheral drainage and blood flow disorders in human extremities which makes it possible to detect by measuring technology the evacuation and filling of dermal vessels--veins and arteries--non-invasively, objectively and quantitatively.

Abstract: An internal combustion piston engine comprises a cylinder with a cylinder bore therein; a cylinder head mounted on said cylinder; a piston reciprocably movable in said cylinder bore, and a main combustion chamber formed between the cylinder head and the piston. At least one secondary combustion chamber is arranged to be connected at least temporarily to the main combustion chamber via at least one connecting channel whereby different compressions and hence different pressure rises occur during the compression stroke or the expansion stroke of the piston in the main combustion chamber or in the secondary combustion chamber. Control means are arranged in the zone of the connecting channel to enable the flow of the gases, which are under a higher pressure, from the main combustion chamber into the secondary combustion chamber or vice versa, to generate velocity fields which improve the turbulence, in particular in the quench zones of the main combustion chamber, and hence improve the combustion.
Abstract: A device for determining the timely delivery of compressed gas from compressed-gas containers for ejection and discharge tubes of submarines in which the compressed gas is suppliable via a system-controlled blowout valve comprising a compressed-gas container having a pressure pick-off with a pressure gauge and a converter for producing an electrical signal representing the actual pressure value. Upper and lower desired pressure values in the form of electrical signals are adjustable on transmitters electrically connected to separate comparator stages to which the electrical signal of the actual pressure value and, in each case, one of the signals of the adjusted predetermined values are supplied and by which a timing member having a running time indicator is controlled. The timing member is started when the pressure in the compressed-gas container falls below the adjusted upper pressure value and is stopped when the pressure in the compressed-gas container reaches the adjusted lower pressure value.
Abstract: An arithmetic unit, particularly for floating point operations, is provided in which numeric words with n digits, shifted by any desired number of digits, can be taken, in one step with a duration independent of the extent of the shift, from a shift array which is constructed from tri-state elements in a triangular matrix.
Abstract: Evaporating and cooking of toffee in a closed vessel having an inlet at the base thereof and an outlet towards the top and at one side of the vessel. A toffee premix liquor is continuously fed in the inlet and discharged through the outlet. High speed counter rotating stirrers are provided in the vessel to agitate the liquor in a vigorous and turbulent manner, such as to form the liquor into a vortex, the extremities of which are urged towards the outlet. The vigorous and turbulent agitation of the liquor assists the production of high quality toffee as a continuous process, at a relatively high throughput rate.
Abstract: A burner is disclosed for alternatively burning coal dust or oil. An annular housing includes a blower at one end thereof for directing a rotating air stream through the housing. A chamber located downstream from the blower has a plurality of outlet pipes extending downstream therefrom in an annular configuration about an atomizing nozzle and an eddy plate. An adjustable burner head is mounted on the end of each of the outlet pipes, the burner heads being arranged for optimum mixture of coal dust and air, fed from the chamber through the outlet pipes to the burner heads, with the rotating air stream passing about and through a hole in the eddy plate to insure optimum combustion. An oil ignition auxiliary burner having a nozzle between the eddy plate and the outlet end of the chamber serves to ignite the coal dust and air mixture. An atomizing nozzle for feeding atomized oil into the burner is provided as an alternative fuel source.
Abstract: The mechanism for adjusting a lumbar support of a back of an office seat, motor vehicle seat or the like, with a plate-like moulding (4) adjustable perpendicularly to the plane of the seat back serves to make the sitter occupy an anatomically correct posture, the moulding (4) supporting the sitter's back.

Abstract: An extensible handle bar for cleaning and painting tools and the like comprises inner and outer tubes in slidable telescoping relationship, the outer tube having a pair of apertures therein containing inserts. A helically threaded nut extends over the exterior surface of the outer tube and the inserts. The outer surface of each of the inserts includes projecting thread segments which mate with the internal threads of the nut. The internal threads of the nut and the thread segments of the insert each have a conical configuration. Upon rotation of the nut in one direction on the outer tube, the inserts are depressed radially such that the inner surfaces of the inserts press against the outer surface of the inner tube to axially lock the inner and outer tubes together.
Abstract: A method of and an apparatus for actuating printing elements, particularly in matrix printers, is provided. The printing elements undergo a deflection at their free end by electronic measures. At one of their ends the printing elements are driven by at least one stationary clamped drive element, while their free end undergoes a deflection which due to the configuration of the printing element is substantially greater than the deflection of the driven end. The deflection of the free end may be measured and the measured value may be used for the abated return. The drive element operates piezoelectrically or magnetostrictively. The stationary clamping may be effected by a bracing element. Each printing element exhibits a cross section tapering towards the free end. This free end may print directly, or may actuate a further printing unit element.
